The spyglass and the cherry tree - Matt Beighton

It should have been the best time of the year, a whole summer holiday to spend alone in her bedroom. Instead, Skye Thistle is dragged from her home, away from her best friend Arthur and forced to spend the holidays at Ron and Wilma's, her hideously eccentric grandparents.To make matters worse, she is being followed by bright green lights that disappear as soon as she turns towards them. Desperate for a distraction, Skye finds herself in an abandoned lighthouse stood in front of an old brass spyglass. She really should have a quick peek. After all, one look couldn't hurt. Could it?
